Definitions
- the subject of the present invention is a new process for preparation of Fexofenadine.
- Fexofenadine is a drug that has significant antihistamine activity and that has no side effects. (Efficacy and safety of Fexofenadine hydrochloride for treatment of seasonal allergic rhinitis, Bernstein DI et al, Ann. Allergy-Asthma-Immunol. (1997) 79 (5) 443-448.
- Terfenadine itself antihistamine agent (D. Mc Tavish, KL Goa and M. Ferill, "terfenadine: an updated review of its pharmacological properties and therapeutic efficiency, Drug 39, 552-574 (1989)).
- Fexofenadine is currently being prepared chemical, in many stages with lower yield at 10% (US Patents 5,578,610 and 5,581,011).
- Application EP-A-864 653 describes a microbiological transformation process from Terfenadine to Fexofenadine using either Cunninghamella or Absidia as a strain .
- the subject of the invention is a process for the preparation of the compounds of formula (I): characterized in that a bioconversion of the compound or compounds of formula (II) is carried out: with either a culture of a microorganism of the genus Absidia corymbifera, or a culture of a microorganism of the genus Streptomyces, at a pH between 5.0 and 8.0, in order to obtain the compound or compounds of formula (I) expected, which if necessary are isolated, purified and / or salified, the compounds of formulas (I) or (II) possibly being in the two possible enantiomeric forms, isolated or in mixtures.
- the asterisk indicates the position of the asymmetric carbon.
- the invention particularly relates to a preparation process as described above in which the Absidia c orymbifera is Absidia corymbifera LCP 63-1800 or in which the Streptomyces is Streptomyces platensis NRRL 2364.
- Fexofenadine is a racemic mixture of enantiomers of formula (I).
- the process therefore has more particularly for object the method as described above in which we carry out a bioconversion of Terfenadine, corresponding to a racemic mixture of the two enantiomers of formula (II), in order to obtain Fexofenadine, corresponding to a racemic mixture of the enantiomers of formula (I).
- Absidia corymbifera and in particular Absidia corymbifera LCP 63-1800 are available at the Cryptogamy Laboratory of the Museum of Natural History in Paris.
- the possible purification step is basically only to eliminate a secondary product which can be formed during bioconversion, namely the triolphosphate which corresponds to alcohol not yet oxidized to acid, esterified in the form of a phosphate (formula (IIIb)) described below.
- the purification is carried out according to the known methods of the skilled person. It can be a purification by crystallization, by chromatography or by exchange resin ion.
- Salification reactions can be carried out under usual conditions. We operate for example in presence of ethanolic soda. You can also use a sodium salt such as carbonate or acid carbonate of sodium or potassium.
- the salts obtained can be alkali or alkaline earth or ammonium salts possibly substituted.
- the oxidation is carried out according to the commonly used methods for microbiological oxidation organic molecules using cultures of filamentous fungi (Holland HL, Organic synthesis with oxidative enzymes. VCH publisher, Inc, New York 1992; Lacroix I, Biton J and Azerad R, Microbial biotransformation of a synthetic immunomodulating agent HR325, Bioorg. Med. Chem. (1997) 7, 1369-1380; Sebek OK, Fungal transformations as a useful method for the organic synthesis of organic compounds, Mycologia 75 (2) 383-394, 1983 Azerad, R. Microbial models for drug metabolism, Advances in Biochemical Engineering and Biotechnology, Vol. 63, page 169, 1999.
- the fermentation conditions more favorable, such as the choice of environment nutrient, appropriate substrate solvent, concentration substrate, technical conditions such as temperature, ventilation, pH, and optimum periods for culture, addition of substrate and contact of substrate with the microorganism.
- the culture is carried out from an inoculum (spores or mycelium) of Absidia corymbifera LCP 63-1800 or from a bacterium of the genus Streptomyces, in particular Streptomyces platensis NRRL 2364, in a liquid nutritive medium with an initial pH of 5 to 7 and at a temperature of 20 to 30 ° C, preferably from 26 to 28 ° C.
- Aeration is ensured by rotary agitation of the culture vessels (150 to 250 rpm) or, in a fermenter, by introduction of air at a flow rate of approximately 1 l / min and per liter of culture broth.
- terfenadine is added to a concentration from 0.1 to 1 g / liter, preferably 0.4 to 0.6 g / liter, in solution in an organic solvent miscible with water, such as ethanol, acetone, tetrahydrofuran, dimethylformamide or dimethyl sulfoxide (5 to 20 ml / liter of culture), preferably ethanol (10 ml / liter).
- an organic solvent miscible with water such as ethanol, acetone, tetrahydrofuran, dimethylformamide or dimethyl sulfoxide
- PH is eventually readjusted and kept at a value of 5.0 to 8.0.
- the transformation of the substrate is advantageously monitored by HPLC analysis of the incubation supernatant or chromatography as a thin layer of samples extracted by a organic solvent. In general after 48 to 200 hours, it has formed sufficient amounts of exofenadine.
- Another procedure is to separate the biomass from the culture medium by filtration, wash with water or buffered solution of neutral pH, then put it back suspension in a suitable buffer, for example a buffer 0.05 M phosphate at pH 7, then add the substrate and continue the incubation as described above.
- a suitable buffer for example a buffer 0.05 M phosphate at pH 7, then add the substrate and continue the incubation as described above.
- Isolation and purification of process products are carried out in a manner known per se.
- a solvent organic preferably ethyl acetate
- a hydrophobic column followed by elution with a organic solvent, evaporate the organic solvent, separate and purify the products by column chromatography or by crystallization.
- One of the objectives of the invention is to adjust the pH to during the incubation and possibly keep it at a optimized value, in order to minimize the formation of secondary products.
- Terfenadine (II) into Fexofenadine (I) by A. corymbifera or S. platensis involves several successive stages, with the intermediate formation of triol (IIIc) and that of two unwanted secondary products, Terfenadine phosphate (IIIa) and the triolphosphate (IIIb) according to the diagram below:
- the invention also relates to intermediate compound, the compound of formula (IIIc), such as defined above.
- 250 ml erlens containing 100 ml of culture medium are inoculated with a suspension of freshly harvested spores on solid medium and growth is carried out in a rotary incubator at 27 ° C and 200 RPM for 66 hours.
- Terfenadine is added in solution in ethanol (10 ml / liter) at a final concentration of 0.2 g / l directly to biomass in its culture medium.
- terfenadine (II) has a retention time of 14.56 min., terfenadine-P (IIIa), a retention time of 11.8 min., triol (IIIc), a retention time of 9.61 min., fexofenadine, a retention time of 9.45 min. and triol-P (IIIb), a retention time of 7.43 min.

- the biomass obtained after 66 hours of culture and which is in the form of homogeneous pellets of about 1 mm in diameter was used for bioconversion directly in the culture fermenter. 1.25 g of Terfenadine in 50 ml of ethanol are added and the incubation is continued under the same conditions for 7 days.
- the pH is 8.5 and the incubation medium contains 35% fexofenadine and 65% triolphosphate.
